Playing a Limited Duration of a Sequence
Long sequences with many effects can be time-consuming to work with in the Timeline.
Working with a shorter sequence can save time. The Play Length Toggle feature lets you switch
between playing the entire sequence and playing a limited duration centered around the current
position of the sequence. When you use the Play Length Toggle feature, the Play button and Play
Length Toggle button change to white.
To play a limited duration of a sequence:
1. Map the Play Length Toggle button from the Play tab of the Command palette to a monitor
toolbar button.
For information about mapping buttons, see “Understanding Button Mapping” on page 110.
2. Move the position indicator to the location where you want to start playing the sequence.
3. Click the Play Length Toggle button.
The Play button and the Play Length Toggle button change to white, indicating the Play
Length Toggle feature is active.
4. Click the Play button.
The sequence plays for the default Play Length, which is 1 minute.
5. To set the Play Length back to play the entire sequence, click the Play Length Toggle button
again.
Understanding Sync Breaks
Sync breaks occur when a frame-accurate relationship between two clips or between the audio
and video tracks within a single clip is offset during editing. Your Avid editing application
provides several features to avoid, track, and remove sync breaks.
In many cases, sync breaks are the unavoidable result of selecting only one track in a synced
relationship (for example, audio only or video only), and performing edit functions that change
the duration of that track when you extract, splice-in, or add or remove frames.
